Cladding Mode Free Photosensitive Single-Mode Fiber - 1

Cladding Mode Free Photosensitive Single-Mode Fiber Nufern's Cladding Mode Free (CMF) fiber is designed to allow more uniform grating-writing in WDM applications. CMF virtually eliminates all cladding modes allowing tighter channel spacing for high speed communications. Cladding Mode Free fiber is mode-matched to SMF-28TM for telecommunication system use. The polyimide coated CMF fiber is ideally suited for use in a WDM distributed sensing networks operating in high temperature and harsh environments. Typical Applications Polyimide Version: Sensors Features & Benefits Excellent cladding mode suppression — allows for tighter channel spacing Mode matched to conventional transmission fibers — low splice loss (<0.1 dB typically) Polyimide Version: High Temperature coating — enables distributed WDM sensing in harsh environments Optical Specifications Mode Field Diameter 9.1 ± 0.5 pm @ 1550 nm 9.1 ± 0.5 pm @ 1550 nm Geometrical & Mechanical Coating Material UV Cured, Dual Acrylate Polyimide Operating Temperature Range -55 to 85 °C -65 to 300 °C Short Term Bend Radius > 6 mm s 12 mm Long Term Bend Radius s 13 mm s 25 mm Prooftest Level > 200 kpsi (1.4 GN/m2) > 100 kpsi (0.7 GN/m2) 7 Airport Park Road, East Granby, CT 06026 • 860.408.5000 • Toll-free 866.466.0214 • Fax 860.844.0210 E-mail info @ nufern.com • www.nufern.com Nufern products are manufactured under an ISO 9001:2008 certified quality management system.
